4 Claims.

This invention relates to new and useful improvements in containerbodies and methods of making the same and more particularly tocorrugated containers such as boxes, cartons and the like having aplurality of wall thicknesses.

The principal object of the present invention is to provide a novelcontainer body of the character set forth having a plurality of wallthicknesses constructed and arranged to provide an offset shoulderconstruction for the reception and seating of a cover or closure member.

Another object of the present invention is to provide a novel method formaking containers of the character set forth wherein machining orotherwise cutting away a portion of one wall section to produce anoffset shoulder construction is entirely eliminated.

A further object of the invention is to provide a novel method formaking containers of the stated character having an off-set shoulderconstruction adjacent one or both ends of said containers eitherinternally or externally thereof.

A still further object of the present invention is to provide a novelmethod for making con- 5 tainers of the character stated which rendersmanufacture of the same comparatively simple and inexpensive.

Other objects of the invention and the features and details ofconstruction thereof are set forth hereinafter and shown in theaccompanying drawings, in which:

Referring now to the drawings, the invention contemplates in general theformation of a continuous composite run of board having a plus rality ofcorrugated wall thicknesses wherein one wall thickness is of less widththan other wall thicknesses thereof, as for example, in the manner shownin Fig. 1 of the drawings wherein a continuous run of single-facedtransversely corrugated board A is fed by means of a roll 'I intoparallel contact with the adjacent liner or facing of a continuous runof double-faced transversely corrugated board B passing intermediatesaid roll I and another roll 2 disposed in opposition thereto. Thesingle-faced run A is fed into contact with the double-faced run B sothat the exposed ridges of the corrugations of the former contact thefacing or liner of the latter, said runs A and B being secured togetherto form a continuous. composite double-walled run C by means of adhesivepreviously applied to the ridges of said corrugations of the run A froma paste box 3 by rolls 4. The composite run C passes intermediate aseries of rolls 5 and steam plates or other suitable heating elements 6where the same is dried and thereafter passes intermediate rolls 1 and8, one of which is provided with an adjustable cut-off element 9operable to sever sections or blanks D from said composite run C atpredetermined intervals transversely thereof.

While the foregoing description and illustration relates particularly tothe manufacture of container blanks having a plurality of corrugatedwall thicknesses wherein the axes of the corrugations of each aresubstantially parallel, said invention is equally adaptable to themanufacture of container blanks having a plurality of corrugated wallthicknesses wherein the axes of the corrugations of each are disposedsubstantially at right-angles to the axes of the corrugations ofadjacent wall thicknesses in accordance with any one of the severalmethods of making corrugated board disclosed in U. S. Letters Patent No.

' One such method of making corrugated board of the above character isdiagrammatically shown 7 inpart in Fig. 8 of the drawings hereof,wherein pre-formed single-faced sheets of corrugated board B aresuccessively fed in abutting relation by continuously moving dogs l intoparallel contact with a continuously fed independent run of liner orfacing sheet II. The facing sheet I l is fed so that the same contactsthe exposed ridges of the corrugations of said pre-formed sheets 3' andis secured thereto to form a substantially continuous double-faced run Eby means of adhesive previously applied to said corrugations from apaste box I2 by rolls l3. In this ramification of the invention the axesof the corrugations of the pro-formed sheets B extend in the directionof feed thereof and substantially at rightangles to the axes of thecorrugations of the continuous run of single-faced transverselycorrugated board A which is fed by a roll l4 into parallel contact withthe liner or facing I I of the previously described compositedouble-faced run E passing intermediate said roll 14 and a roll ldisposed in opposition thereto. As shown the exposed ridges of thecorrugations of the singlefaced run A contact the facing or liner l l ofthe run E and the same is secured thereto by means of adhesivepreviously applied to said corrugations from the paste box 3 by rolls 4to form a continuous composite double-walled run C, the axes of thecorrugations of adjacent wall thicknesses of which are disposedsubstantially at right-angles to each other.

The composite run C then passes intermediate the rolls 5 and steamplates or other suitable heating elements 6, where the same is dried andthere after passes intermediate the rolls 1 and 8, one of which carriesthe adjustable cut-off element 9 operable to cut sections or blanks Dvfrom said composite run C at predetermined intervals transverselythereof.

In the foregoing descriptions, it is to be particularly observed that ineach instance one particular wall thickness is of greater width thanothers so that the latter project a predetermined distance beyond atleast one side edge of the former as shown, and therefore the containerblanks D and D severed from the composite runs C and C respectively willlikewise comprise a plurality of wall thicknesses wherein one of saidthicknesses is of less width than others as disclosed in Figs. 2 and 9of the drawings. However, it is pointed out that the invention may bepracticed with equal effectiveness by reversing the relative dimensionsof said wall thicknesses so that the present narrower wall thickness isof greater width than others.- Furthermore, in certain instances it maybe desirable to form container blanks wherein one wall thicknessprojects beyond two opposite side edges of the other wall thicknessesthereof as shown in Figs. 5 and 12 of the drawings, and container blanksof this particular character, designated generally as F and Frespectively, may be formed in the manner disclosed in Figs. 1 and 8 byforming wall thicknesses having predetermined relative widths andpositioning the same transversely with respect to in Figs. 2 and 5thereof.

After the container blanks have been severed from the composite runs inthe manner previously described, the same are scored transverselythereof parallel to their end edges H5 at predetermined spaced intervalsdepending upon whether a container having a corner or side wall seam isdesired, and, for example, in the former instance the blanks are scoredtransversely at equally spaced intervals with respect to each other andthe transverse end edges l6 thereof as indicated at I! in Figs. 2 and 9of the drawings so that the line of abutment of said end edges willreside at a corner of a container, and in the latter instance the blanksare similarly scored transversely at predetermined spaced intervals asindicated at I 8 in Figs. 5 and 12 so that the line of abutment of theopposite end edges IE will reside in a side wall portion of a containerbody.

The container bodies are formed by bending the blanks previouslydescribed along their several transverse scores I! and I8 respectively,to place the opposite end edges l6 of each in substantially abuttingrelation as shown in Figs. 3, 6, 10, and 13 of the drawings, said endedges being secured in the aforementioned abutting re lation by anysuitable means such as an adhesive strip or the like IS. The containerbodies may be formed so that the narrower wall thicknesses are disposedexternally or internally of the wall thicknesses of greater width as maybe desired, and in the former instance disposition of said narrower wallthickness externally of the other wall thicknesses, produces a shoulder20 on the exterior of said container body which terminates at its inneredges in a projecting sleeve portion 2| formed by the inner wallthickness. Similarly, formation of a container body with the narrowerwall thickness disposed internally of the other produces a shoulder 22in the interior of said container body which terminates at its outeredges in a projecting sleeve portion 23 formed by the outer wallthickness.

In the present instance the projecting sleeve portions 2| of thecontainer bodies shown in Figs. 3 and of the drawings are arranged toreceive closure members 24 which overlie the same in abutting relationwith respect to the external shoulders thereon, and the projectingsleeve portion 23 of container bodies illustrated in Figs. 6 and 13 arearranged to receive similar closure members 25 which are insertedinwardly of said sleeve portions 23 in the manner shown in either Figs.7 or 14 in abutting relation with respect to the internal shoulders 22.

While the invention has been illustrated and described in connectionwith corrugated or like container bodies of tubular form and open at theends, it will be obvious that the novel shoulder and projecting sleeveconstruction herein disclosed and forming the subject of the presentinvention may be embodied in the manufacture of still other types ofcontainers or container bodies whether of the tubular, open-ended formshown, or provided with integral inclosure flaps at one end thereof, ofthe general character disclosed in my co-pending application for LettersPatent of the United States bearing Serial No.
